I live in the black hills in south dakota and the humidity around here is really really low. Ive been havin trouble gettin the humidity up past 30% or 40% for my russian tortoise. I have moss in the tank and i mist it 3 or 4 times a day but it still dont work. Does anyone have any suggestions to get it up higher? I live on military housing so i cant do any crazy things to my house or anything.
